# 如何创建验证器密钥？

### **Prerequisites** 先决条件

a. 兼容的钱包（目前仅支持 Metamask），可容纳超过 32 个 Eth

 **b.** 生成 deposit\_data-timestamp.json，可通过 deposit-cli 工具 [**deposit-cli tool**](https://github.com/ethereum/staking-deposit-cli/releases/) 完成。 具体来说，我们真正需要的是 deposit\_data-timestamp.json 中的 withdrawal\_credentials

{% hint style="info" %}
Specifically, what we actually need is the `withdrawal_credentials` within the `deposit_data-timestamp.json`
{% endhint %}

### 1.  生成 `deposit_data`/`withdrawal_credentials` 

**步骤 1：**在此处下载 [**存款 CLI 应用程序**](https://github.com/ethereum/staking-deposit-cli/releases/)，确保您已为您的操作系统选择了正确的应用程序。

请确保您是从以太坊基金会的官方 **GitHub 帐户** 下载的 -  <https://github.com/ethereum/staking-deposit-cli/releases/>
{% endhint %}

**步骤 2：**&#x4E0B;载完成后，解压下载的文件。

**步骤 3：**&#x6253;开您的命令行/终端。

**步骤 5：**&#x4F7F;用以下命令运行可执行文件   `deposit.exe new-mnemonic --num_validators 1 --chain mainnet` （适用于 Windows）和  `./deposit new-mnemonic --num_validators 1 --chain mainnet` （适用于 Linux 或 MacOS）。

&#x20;**步骤 6**：请记下助记词并找到 `deposit_data` 文件
